There’s a free demo available which will nag you after a bit; if you find it useful, interesting, helpful, or even just a little fun, it would be great if you purchased Clojure Atlas for whichever version(s) of Clojure you’re interested in.

Please note that Clojure Atlas is by no means Done, or even “done”. I’m opening it up for use and purchase now in the spirit of release early, release often, so you are sure to find rough edges in the UI and straightforward incompleteness in the ontology that drives the Atlas. You can read more about the current status here.

As for what’s in the future for Clojure Atlas, my personal to-do list is far too long to go into. Part of why I’m releasing it “early” is to get a sense of what people want, and what will be most useful. Doing otherwise would surely lead me to fritter away precious days and weeks honing features interesting to only a few. There are links all over the site and in the Atlas itself where you can submit ideas, suggestions, and bug reports via all sorts of channels; I’ll be keeping a close eye on the email, tweets, and UserVoice threads submitted in order to filter and prioritize future work.

P.S. I’d like to thank all of the early-access testers that provided valuable feedback leading up to this release. In particular, Edmund Jackson spent far more time with me on irc than he needed to, helping to ferret out issues in the earlier revisions of the graph visualization, and making a variety of excellent suggestions for future development.

The question is, high compared to what? Open source software? Sure. Programming books? Hardly. Everyone needs to make their own decision as to whether the value provided by Clojure Atlas justifies its price.

In any case, I need to justify the work needed to build the ontologies (there’s a different one for each version of Clojure) as well as continue improving the user experience. I’ve only just released the product, so I’ve not yet done any experimentation on the price front.
